System and method for data validation

ABSTRACT

Systems and methods for validating data in a communication network environment include receiving a data transformation specification from a user. The data transformation specification is analyzed to determine data transformation rules which are indicative of a relationship between corresponding fields of the source repository and the target repository. Test cases and test scripts are generated based on the data transformation rules and the test cases and the test scripts are executed on the source repository and the target repository to validate the relationship between the corresponding fields of the source repository and the target repository. Thereafter, a log file, indicative of the outcome of the execution of the test cases and the test scripts, is generated.

This is a continuation of U.S. patent application Ser. No. 14/260,033, filed Apr. 23, 2014 which claims the benefit of Indian Patent Application No. 1267/CHE/2014 filed Mar. 11, 2014, which is hereby incorporated by reference in its entirety.

FIELD

The present subject matter is related, in general to data validation and, in particular, but not exclusively to a method and system for validating data in a communication network environment.

BACKGROUND

In recent time, most of the organizations use various systems and methods to manage their day to day working. Examples of such software tools may include enterprise resource planning (ERP) systems, customer relationship management (CRM) systems, and supply chain management (SCM) systems. Each of these software tools is associated with various data repositories and has its own respective data model. Examples of data stored in the data repositories include customer data, transaction data, business research data, and so on.

It is well known, by those skilled in the art, that each of the software tools may use, retrieve and store the data in different formats. Further, in an organization, the various software tools, configured to manage the day to day working of the organization, are often interlinked. This makes it important that the data used and stored by each of these software tools are accurate, updated and consistent.

However, with time, various changes take place in the organization which may involve installation of new applications, re-platforming of applications, migration of data repositories from one vendor to a different vendor and so on. In many situations, this involves migrating the data from an existing data repository to a new data repository.

During this migration, many errors, such as system field limitations, mergers and migrations, data repository migrations, inconsistent standards, discrepancies in data format, difference in structure of data repositories, missing data, data fields filled with default values or nulls, spelling errors and data anomalies, may creep in and degrade the quality of data. This adversely affects the functioning of the new application or re-platformed application or the new data repository. Erroneous data transformation may adversely impact the functioning of the organization. For example the organization having erroneous data transformation processes may suffer from losses arising from extra costs to prepare reconciliations, delay or scrapping migration to a new application or new data repository, failure to bill or collect receivables, inability to deliver orders, failure to meet contracts and so on. The erroneous data can also lead to incompetent future decisions of enterprise and has the potential to negatively impact the growth of the enterprise.

SUMMARY

Disclosed herein are systems and methods for validating data in a communication network environment. In one example, the system for validating data, in a communication network environment, comprises a processor, a memory communicatively coupled to the processor. The system further comprises a processor and a memory communicatively coupled to the processor, wherein the memory stores processor-executable instructions, which, on execution, cause the processor to receive a data transformation specification from a user; analyze the data transformation specification to determine data transformation rules, wherein the data transformation rules are indicative of a relationship between corresponding fields of the source repository and the target repository; generate test cases and test scripts based on the data transformation rules; execute the test cases and the test scripts on the source repository and the target repository to validate the relationship between the corresponding fields of the source repository and the target repository; and generate a log file indicative of the outcome of the execution of the test cases and the test scripts.

In an aspect of the invention, the method, for validating data in a communication network environment, comprises a data transformation specification from a user and analyzing the data transformation specification to determine data transformation rules, wherein the data transformation rules are indicative of a relationship between corresponding fields of the source repository and the target repository. The method further comprises generating test cases and test scripts based on the data transformation rules and executing the test cases and the test scripts on the source repository and the target repository to validate the relationship between the corresponding fields of the source repository and the target repository. Thereafter, a log file, indicative of the outcome of the execution of the test cases and the test scripts, is generated

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.

DETAILED DESCRIPTION

In the present document, the word “exemplary” is used herein to mean “serving as an example, instance, or illustration.” Any embodiment or implementation of the present subject matter described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

Systems and methods for validating data in a communication network environment are described herein. The systems and methods may be implemented in a variety of computing systems. The computing systems that can implement the described method(s) include, but are not limited to a server, a desktop personal computer, a notebook or a portable computer, a mainframe computer, and in a mobile computing environment. Although the description herein is with reference to certain computing systems, the systems and methods may be implemented in other computing systems, albeit with a few variations, as will be understood by a person skilled in the art.

In recent time, most of the organizations use various systems and methods to manage their day to day working. Examples of such software tools may include enterprise resource planning (ERP) systems, customer relationship management (CRM) systems, and supply chain management (SCM) systems. Each of these software tools is associated with various data repositories and has its own respective data model. Examples of data stored in the data repositories include customer data, transaction data, business research data, and so on.

It is well known, by those skilled in the art, that each of the software tools may use, retrieve and store the data in different formats. With time, the organization may decide to update the installed applications or replace the installed applications with different applications or replace the data repositories or even re-platform the installed applications. In many situations, the new/updated applications or data repositories may have different data formats, data types and so on. Hence, while transforming the data from a source data repository to a target data repository various data transformation rules are determined which state the relationship between corresponding tables/fields of the source data repository and the target data repository. The data transformation operation converts a set of data values from the data format of the source data repository into the data format of the destination data repository. The data transformation operation is usually carried out in two steps. In the first step, the corresponding fields and tables of the source data repository and the destination data repository are mapped. Thereafter, a code snippet is generated which on execution causes the actual data transformation. In most conventional systems, the data transformation rules are then tested manually to ensure that the data transformation has been performed without any errors. However, the conventional techniques for verifying data transformation involve a substantial amount of manual actions or manual interventions. Further, in many cases mapping the data transformation may be from multiple data sources, for example, multiple databases stored in the source data repository. In such situations, preserving data integration and synchronization functionality becomes very challenging. Hence, various errors, such as data entry errors, limited validation of data at the time of entry, system field limitations, mergers and migrations, data repository migrations, inconsistent standards, discrepancies in data format, difference in structure of data repositories, missing data, data fields filled with default values or nulls, spelling errors and data anomalies may creep in which may adversely affect the functioning of the new/updated applications or data repositories.

The present subject matter discloses systems and methods for validating data in a communication network environment. In one implementation, a data validation system, also referred to herein as a data validation apparatus, validates the data transformation processes when transferring data from a source data repository to a target data repository. The source data repository and the target data repository may be implemented using any conventional database systems such as Sybase™, MySQL™, DB2™, SQL Server™, Oracle™. It should be appreciated by those skilled in the art that though the systems and methods for validating data in a communication network environment are described in the context of validating data transformations when migrating from the source data repository to the target data repository, the same should not be construed as a limitation. For example, the systems and methods for validating data in a communication network environment may be implemented for various other purposes, such for determining data consistency, and determining compatibility of data repository with applications.

In one example, the data validation system prompts the user to input a data transformation specification. In one example, the data transformation specification may include the schema of the source data repository and the target data repository and also include the rules, in human readable language, based on which the data transformation is to be done. On receiving the data transformation specification, the data validation system parses the same and processes the parsed data transformation specification to generate data transformation rules. The data transformation rules may comprise assign rules which assign a default value to particular fields, pattern-Replace rules in which patterns, in the values of the fields, are replaced, replace rules in which the values of the fields are replaced, and truncate rules in which if the length of the value of the field exceeds a pre-defined length, then the rule truncates the value to the pre-defined length.

Thereafter, the data validation system generates the test cases and test scripts to validate the data transformation rules. In one example, the data validation system may be communicatively coupled to any third party testing tool to generate the test cases and test scripts. In yet another example, the user may feed the test cases and test scripts to the data validation system.

On receiving the test cases and the test scripts, the data validation system determines whether the number of data records to be processed, i.e. validated, is more than a critical threshold. If the number of data records to be processed exceeds a critical threshold, then the data validation system initiates a parallel execution of the test cases. If the number of data records to be processed is less than a critical threshold, then the data validation system initiates a serial execution of the test cases. In one example, the data validation system may execute the test cases and test scripts based on the associated data transformation rule. For example, the data validation system may execute test cases associated with data transformation rule ‘N’ before executing test cases associated with data transformation rule ‘M’. This may facilitate the data validation system to exit the validation process on determining the data transformation rule ‘N’ to have been violated and thus, save processing power and memory resources by not executing data transformation rule ‘M’. In one example, the data validation system may determine the sequence of execution of test cases and test scripts based on the optimized use of processing power and memory.

On completion of the execution of the test cases and test scripts, the data validation generates a log file. The log file indicates the result of the test cases and mentioned the data transformation rules that have been validated and the data transformation rules that have been violated. In one example, the log file may mention the primary key or the record number of the records which have violated the data transformation rules. Thus, the data validation system implements a fast data validation process which eliminates manual intervention and hence, eliminates errors caused due to manual processing. The data validation system also eliminates the errors caused due to difference in understanding, of different testing professionals, of the data transformation specification.

The working of the systems and methods for validating data in a communication network environment is described in greater detail in conjunction with FIG. 1-4. It should be note that the description and drawings merely illustrate the principles of the present subject matter. It will thus be appreciated that those skilled in the art will be able to devise various arrangements that, although not explicitly described or shown herein, embody the principles of the present subject matter and are included within its spirit and scope. Furthermore, all examples recited herein are principally intended expressly to be only for pedagogical purposes to aid the reader in understanding the principles of the present subject matter and are to be construed as being without limitation to such specifically recited examples and conditions. Moreover, all statements herein reciting principles, aspects, and embodiments of the present subject matter, as well as specific examples thereof, are intended to encompass equivalents thereof. While aspects of the systems and methods can be implemented in any number of different computing systems environments, and/or configurations, the embodiments are described in the context of the following exemplary system architecture(s).

FIG. 1 illustrates a network environment 100 implementing a data validation system 102 for validating data in a communication network environment, according to some embodiments of the present subject matter. In one implementation, the data validation system 102 may be included within an existing information technology infrastructure of an organization. For example, the data validation system 102 may be interfaced with the existing content and document management system(s), database and file management system(s), of the organization.

The data validation system 102 may be implemented in a variety of computing systems, such as a laptop computer, a desktop computer, a notebook, a workstation, a mainframe computer, a server, a network server, and the like. It will be understood that the data validation system 102 may be accessed by users through one or more client devices 104-1, 104-2, 104-3, 104-N, collectively referred to as client devices 104. Examples of the client devices 104 include, but are not limited to, a desktop computer, a portable computer, a mobile phone, a handheld device, a workstation. The client devices 104 may be used by various stakeholders or end users of the organization, such as project managers, database administrators and application developers. As shown in the figure, such client devices 104 are communicatively coupled to the data validation system 102 through a network 106 for facilitating one or more end users to access and/or operate the data validation system 102.

The network 106 may be a wireless network, wired network or a combination thereof. The network 106 can be implemented as one of the different types of networks, such as intranet, local area network (LAN), wide area network (WAN), the internet, and such. The network 106 may either be a dedicated network or a shared network, which represents an association of the different types of networks that use a variety of protocols, for example, Hypertext Transfer Protocol (HTTP), Transmission Control Protocol/Internet Protocol (TCP/IP), Wireless Application Protocol (WAP), etc., to communicate with each other. Further, the network 106 may include a variety of network devices, including routers, bridges, servers, computing devices, storage devices, etc.

In one implementation, the data validation system 102 includes a processor 108, a memory 110 coupled to the processor 108 and interfaces 112. The processor 108 may be implemented as one or more microprocessors, microcomputers, microcontrollers, digital signal processors, central processing units, state machines, logic circuitries, and/or any devices that manipulate signals based on operational instructions. Among other capabilities, the processor 108 is configured to fetch and execute computer-readable instructions stored in the memory 110. The memory 110 can include any non-transitory computer-readable medium known in the art including, for example, volatile memory (e.g., RAM), and/or non-volatile memory (e.g., EPROM, flash memory, etc.).

The interface(s) 112 may include a variety of software and hardware interfaces, for example, a web interface, a graphical user interface, etc., allowing the data validation system 102 to interact with the client devices 104. Further, the interface(s) 112 may enable the data validation system 102 respectively to communicate with other computing devices, The interface(s) 112 can facilitate multiple communications within a wide variety of networks and protocol types, including wired networks, for example LAN, cable, etc., and wireless networks such as WLAN, cellular, or satellite. The interface(s) 112 may include one or more ports for connecting a number of devices to each other or to another server.

In one example, the data validation system 102 includes modules 114 and data 116. In one embodiment, the modules 114 and the data 116 may be stored within the memory 110. In one example, the modules 114, amongst other things, include routines, programs, objects, components, and data structures, which perform particular tasks or implement particular abstract data types. The modules 114 and may also be implemented as, signal processor(s), state machine(s), logic circuitries, and/or any other device or component that manipulate signals based on operational instructions. Further, the modules 114 can be implemented by one or more hardware components, by computer-readable instructions executed by a processing unit, or by a combination thereof.

In one implementation, the modules 114 further include a user input module 118, a test data workflow module 120, a data transformation validation module 122, a data access module 124, a script generation module 126, and other modules 128. The other modules 128 may perform various miscellaneous functionalities of the data validation system 102. It will be appreciated that such aforementioned modules may be represented as a single module or a combination of different modules.

In one example, the data 116 serves, amongst other things, as a repository for storing data fetched, processed, received and generated by one or more of the modules 114. In one implementation, the data 116 may include, for example, transformation rules repository 130, temporary data 132, validation reports repository 134, and other data 136. In one embodiment, the data 116 may be stored in the memory 110 in the form of various data structures. Additionally, the aforementioned data can be organized using data models, such as relational or hierarchical data models. The other data 136 may be used to store data, including temporary data and temporary files, generated by the modules 114 for performing the various functions of the data validation system 102.

In one implementation, the data validation system 102 is communicatively coupled with a source data repository 138 and a target data repository 140. The source data repository 138 and the target data repository 140 may comprise one or more commercially available data storage media, such as compact discs, magnetic tapes, SATA disks, and so on. The source data repository 138 and the target data repository 140 may also implement various commercially available database management systems, such as Oracle™ Database, and Microsoft™ SQL Server. In one example, the source data repository 138 and the target data repository 140 stores raw data which may be further accessed or processed by various applications used in the organization or its clients. In one implementation, the source data repository 138 and/or the target data repository 140 may be implemented within the data validation system 102.

In operation, the user input module 118 prompts the user to input a data transformation specification. In one example, the user input module 118 may generate various graphical user interfaces and/or command line interfaces to facilitate the user to enter the data transformation specification. In one example, the data transformation specification may the schema of the source data repository 138 and the target data repository 140. The user input module 118 may facilitate the user to view the schemas in a graphical manner, for example, in form of a tree structure, to facilitate easy creation of mappings of the corresponding fields and tables of the source data repository 130 and the target repository 140. In one example, the user input module 118 may facilitate the user to drag and drop fields from the source data repository 138 to the target data repository 140 for the purpose of creating mappings.

In one implementation, the user input module 118 further prompts the user to input the configuration parameters of the source data repository 138 and the target data repository 140. The configuration parameters may include the authentication details, such as username and password, to access the source data repository 138 and the target data repository 140, the internet protocol (IP) addresses of the source data repository 138 and the target data repository 140, the port numbers on which the source data repository 138 and the target data repository 140 are operating, the protocol to access the source data repository 138 and the target data repository 140 and so on. On receiving the configuration parameters, the data access module 124 validates the configuration parameters and ascertains whether connection with the source data repository 138 and the target data repository 140 can be established with the received configuration parameters.

In one example, the test data workflow module 120 analyzes the data transformation specification to generate data transformation rules. In one example, the test data workflow module 120 parses the data transformation specification to determine the data transformation rules. The data transformation rules are indicative of the relationship between the values of the corresponding fields of the source data repository 138 and the target data repository 140. The data transformation rules may modify the values or the patterns in values while transforming from the source data repository 138 to the target data repository 140. The data transformation rules may be clubbed with conditional rules so as to modify the values or patterns only in fields of the source data repository 138 that meet the pre-defined criteria. In one example, the test data workflow module 120 may store the data transform rules as transformation rules repository 130.

Thereafter, the test data workflow module 120 generates test cases for validating the data transformation rules. In one implementation, the test data workflow module 120 may be communicatively coupled with any commercially available testing tool for the purpose of creation of test cases. In one example, the test data workflow module 120 also facilitates the user to select the test cases for testing the data transformation rules. Thereafter, the script generation module 126 generates test scripts for executing the test cases.

In one example, the script generation module 126 may generate the test scripts in a way so as to execute the test cases based on the associated data transformation rule. For example, the script generation module 126 may execute test cases associated with data transformation rule ‘N’ before executing test cases associated with data transformation rule ‘M’. On completion of the generation of test scripts, the data transformation validation module 122 executes the test scripts. The order in which the test cases are to be executed facilitates the data transformation validation module 122 to exit the validation process on determining the data transformation rule ‘N’ to have been violated and thus, save processing power and memory resources by not executing data transformation rule ‘M’. In one example, the data transformation validation module 122 may determine the sequence of execution of test cases and test scripts based on the optimized use of processing power and memory.

On completion of the execution of the test cases and test scripts, the data transformation validation module 122 generates a log file. The log file indicates the result of the test cases and mentioned the data transformation rules that have been validated and the data transformation rules that have been violated. In one example, the log file may mention the primary key or the record number of the records which have violated the data transformation rules.

In one example, the data transformation validation module 122 may generate various reports from the log files which may be used by the users, such as developers and/or database administrators, to analyze any issues that may have taken place during the data transformation process. For example, the reports may include various statistical data on the data validation process in tabular format or in the form of charts that may provide the user with an overview of the results of the data validation process.

Thus, the data validation system 102 implements a fast data validation process which eliminates manual intervention and hence, eliminates errors caused due to manual processing. The data validation system 102 also eliminates the errors caused due to difference in understanding, of different testing professionals, of the data transformation specification. The detailed working of the data validation system 102 is further explained in conjunction with the FIGS. 2-4.

FIGS. 2 and 3 exemplary computer implemented methods for validating data in a communication network environment, according to an embodiment of the present subject matter. The methods 200 and 300 may be described in the general context of computer executable instructions. Generally, computer executable instructions can include routines, programs, objects, components, data structures, procedures, modules, and functions, which perform particular functions or implement particular abstract data types. The methods 200 and 300 may also be practiced in a distributed computing environment where functions are performed by remote processing devices that are linked through a communication network. In a distributed computing environment, computer executable instructions may be located in both local and remote computer storage media, including memory storage devices.

The order in which the methods 200, and 300 is described is not intended to be construed as a limitation, and any number of the described method blocks can be combined in any order to implement the methods 200, and 300 or alternative methods. Additionally, individual blocks may be deleted from the methods 200 and 300 without departing from the spirit and scope of the subject matter described herein. Furthermore, the methods 200, and 300 can be implemented in any suitable hardware, software, firmware, or combination thereof.

With reference to method 200 as depicted in FIG. 2, as shown in block 202, a data transformation specification is received from a user. In one example, the user input module 118 may generate various graphical user interfaces and/or command line interfaces to facilitate the user to enter the data transformation specification.

As illustrated in block 204, the data transformation specification is analyzed to generate data transformation rules. In one example, the test data workflow module 120 parses the data transformation specification to determine the data transformation rules.

As depicted in block 206, test cases, and test scripts are generated based on the data transformation rules. In one example, the test data workflow module 120 generates test cases and test scripts based on the data transformation rules.

At block 208, it is determined whether the number of records is above a critical threshold. In one example, the data transformation validation module 122 determines whether the number of records is above a critical threshold.

If at block 208, the number of records is determined to be above the critical threshold, then, as shown in block 210, parallel execution of the test cases and test scripts is initiated. In one example, the data transformation validation module 122 initiates parallel execution of the test cases and test scripts on determining the number of records to be above the critical threshold.

If at block 208, the number of records is determined to be below the critical threshold, then, as shown in block 212, serial execution of the test cases and test scripts is initiated. In one example, the data transformation validation module 122 initiates serial execution of the test cases and test scripts on determining the number of records to be below the critical threshold.

As shown in block 214, a log file is generated, wherein the log file is indicative of the result of comparison of data in a source repository and a target data repository. In one example, the data transformation validation module 122 generates a log file. The log file indicates the result of the test cases and mentioned the data transformation rules that have been validated and the data transformation rules that have been violated.

As illustrated in block 216, a report is generated for data transformation based on the log file. In one example, the data transformation validation module 122 may generate various reports from the log files which may be used by the users, such as developers and/or database administrators, to analyze any issues that may have taken place during the data transformation process.

With reference to method 300 as depicted in FIG. 3, as shown in block 302, a source repository and a target repository is ascertained based on user input. In one example, the user input module 118 prompts the user to enter the identifiers for the source repository and the target repository. The identifiers may be server-name, IP address of the source repository and the target repository, and so on.

At block 304, configuration parameters of the source repository and the target repository are received. In one example the user input module 118 may generate various graphical user interfaces and/or command line interfaces to facilitate the user to enter the configuration parameters of the source repository and the target repository.

As illustrated in block 306, connections are established with the source repository and the target repository. In one example, the data access module 124 establishes the connections are established with the source repository and the target repository using the received configuration parameters.

As depicted in block 308, the data transformation rules are retrieved. In one example, the test data work flow module 120 retrieves the data transformation rules.

At block 310, test cases and test scripts are generated, based on the data transformation rules. In one example, the test data work flow module 120 generates the test cases based on the data transformation rules. Thereafter, the script generation module 126 generates the test scripts for executing the test cases on the source repository and the target repository.

As illustrated in block 312, the test cases and test scripts are executed on the source repository and the target repository. In one example, the data transformation validation module 122 initiates execution of the test cases and test scripts on the source repository and the target repository.

As shown in block 314, at least one report is generated based on the execution. In one example, the data transformation validation module 122 may generate various reports, based on the execution of the test scripts and test cases, which may be used by the users, such as developers and/or database administrators, to analyze any issues that may have taken place during the data transformation process.
